摘要

To revamp a blast furnace (BF) is required about every 15 years, and revamp duration by a conventional method is around 130 days. JFE Steel has developed a new revamping method, so called "Large Block Ring Construction Method." By employing the method, the revamp duration was remarkably reduced to a half of a conventional one. A furnace body (10 000 t) was segmented into blocks of 10 t to 20 t weight during dismantling and installation in conventional method. Blocks by the Large Block Ring Constitution Method weigh over 2 000 t a piece. Consequently, the revamp duration of No. 6 BF at East Japan Works(Chiba) in 1998 was only 62 days, which was the world shortest record of revamp duration. The method was also successfully adopted to No. 5 BF at West Japan works (Fukuyama) in 2005, and established a. new world record of 58 days.
